Problems solved by technology

[0003] Although the above-mentioned patent has the above-mentioned advantages, when it is desired to use the patent to accept two wafers at the same time, two sets of robotic arms must be installed at the same time, and the gripping components of each robotic arm must have a certain distance between them, which will cause : 1. The overall production cost increases, and two sets of power mechanisms must be used to control the movement of each mechanical arm separately
2. The spacing cannot be adjusted according to demand, or the spacing is prone to errors due to use

Embodiment approach

[0067] one,

[0068] see Figure 4 , a position detector 5 is further provided, and the position detector 5 can detect the vertical height of the bottom of the first receiving group body 131 from the first groove 111 to obtain a height detection value; The control unit 2 determines whether the servo motor 16 is stopped or not according to the height detection value.

[0069] Therefore, when the first receiving group body 131 moves to a preset height, the control unit 2 will control the servo motor 16 to stop actuating. In this way, the control between the receiving parts 132 and 142 can be achieved. The purpose of the spacing width. Since the width of each distance is affected by the setting positions of the grooves 111, 112, the purpose of controlling the distances can be achieved only by monitoring the position of the first receiving group body 131 in the first groove 111. In addition, during actual implementation, the above-mentioned purpose can also be achieved by monit...

Abstract

The invention relates to a mechanical arm for controlling the distance between a plurality of bearing pieces. The mechanical arm is mainly characterized in that two grooves are arranged on the side surface of a mechanical arm body, bearing group bodies of two bearing groups are respectively arranged in the grooves, and each bearing group body is propped against the side surface of a connecting rod, so that when a servo motor drives one end of the connecting rod to rotate, the bearing group bodies are driven to move upwards simultaneously. During the moving process, the distance between the bearing pieces at the front sides of the bearing group bodies is gradually increased, the distance is controlled through the ascending degree of the bearing group bodies, and errors of the distance are not prone to being caused along with the influence of the using time.

Description

[0001] Technical field: the creation of the present invention relates to a mechanical arm, especially a mechanical arm that controls the distance between multiple receiving parts. Background technique: [0002] Please refer to China Taiwan Patent Certificate No. M447821 "Vibration Detection Equipment". The test equipment includes a robot arm, a detection mechanism, and an information collection device. The robot arm includes a pick-and-place mechanism for picking and placing the wafer component. When the wafer component is a test wafer, it has a wafer vibration position, and the detection The mechanism includes a detection component capable of detecting vibration, and the detection component is arranged at a vibration sampling position of the robot arm or a wafer vibration position, so as to detect and sample a vibration sampling information corresponding to the vibration sampling position or the wafer vibration position, The information collection device is connected to the d...
